无菌猪的肠道气肿（肠壁囊样积气症）

Can J Comp Med. 1977 Jul;41(3):302-5.

A gnotobiotic pig monocontaminated with an enteropathogenic Escherichia coli was subsequently hyperimmunized to produce a monotypic antiserum. At necropsy, multiple, air filled cysts were found in the wall of the large intestine. The etiology of this condition is still conjectural. However, select strains of E. coli may cause or contribute to intestinal emphysema in swine.

一只单感染肠道致病性大肠杆菌的无菌猪随后被超免疫以产生单型抗血清。尸检时，在大肠壁发现多个充满气体的囊肿。这种情况的病因仍属推测。然而，特定菌株的大肠杆菌可能导致或促成猪的肠道气肿。
